We error for other unsupported options, for example an --enable-targets=all ld

~/build/gas/all/ld$ ./ld-new -m v850 --enable-new-dtags empty.o
./ld-new: unrecognised option '--enable-new-dtags'
./ld-new: use the --help option for usage information
~/build/gas/all/ld$ echo $?
1
~/build/gas/all/ld$ ./ld-new -m v850 --disable-new-dtags empty.o
./ld-new: unrecognised option '--disable-new-dtags'
./ld-new: use the --help option for usage information
~/build/gas/all/ld$ echo $?
1

It has been that way for a long time.  And since binutils-2.22

~/build/gas-2.22/all/ld$ ./ld-new -m v850 -z norelro empty.o
./ld-new: warning: -z norelro ignored.

Yes, I agree it might have been nicer if -z norelro did not warn, but it's been
that way since 2011 and arguably many other options should be treated the same
if unsupported.  So I'm not inclined to see this as a bug that needs fixing.
